[0021] The utility model provides a floating ball lever floating trap, such as Figure 1 As shown, in this embodiment, it includes a valve body and a valve cover, the valve body includes a first shell 1 and a second shell 2, the first shell 1 and the second shell 2 are sealed and connected by a flange, the first shell 1 is provided with a medium inlet channel, the second shell 2 is provided with a medium outlet channel and a drain nozzle, and a drain valve 4 and an exhaust valve 3 are provided inside the first shell 1;
[0022] The drain valve 4 includes a drain valve seat 41 fixedly arranged on the second housing 2, a drain valve cover 42 fixedly arranged on the drain valve seat 41, and a gas blocking valve plate 43. The drain valve cover 42 is provided with three water inlet holes. An active chamber is formed between the drain valve seat 41 and the drain valve cover 42. The gas blocking valve plate 43 is movably arranged inside the active chamber. The gas blocking valve plate 43 can block the drain valve seat 41. A connecting lever 44 can extend into the active chamber and be fixedly connected to the gas blocking valve plate 43. A floating ball 45 is fixedly arranged on the other end of the connecting lever 44. The floating ball 45 can drive the lever 44 to move, so that the gas blocking valve plate 43 is separated from the drain outlet of the drain valve seat 41, so that it is in an open state. After the floating ball 45 falls, it drives the lever 44 to move, so that the gas blocking valve plate 43 blocks the drain outlet of the drain valve seat 41.
[0023] The exhaust valve 3 includes an exhaust valve seat 31 fixedly arranged on the second shell 2, an exhaust valve cover 32 fixedly arranged on the exhaust valve seat 31, and an exhaust valve disc 33. The exhaust valve seat 31 is provided with a water inlet, and a sealed pressure chamber is formed between the exhaust valve seat 31 and the exhaust valve cover 32. The exhaust valve disc 33 is movably arranged inside the pressure chamber. The exhaust valve disc 33 can reciprocate in the pressure chamber with the pressure change on both sides thereof to seal or open the drain port of the exhaust valve seat 31 without the aid of external force. There is only one moving part, the exhaust valve disc 33, in the exhaust valve, and no jamming phenomenon will occur. The exhaust valve 3 also includes an air jacket, which can separate the pressure chamber from the outside world, so that the switching of the exhaust valve is not affected by the temperature change of the external environment. The operating principle of the exhaust valve 3 is the same as that of a conventional thermodynamic steam trap, and an exhaust valve with the same structure as that of a conventional thermodynamic steam trap can be used.
[0024] The float lever floating steam trap has a large diameter, fast drainage and good sealing performance. When the steam enters the valve body, the temperature and pressure are high. After the temperature drops, condensed steam or condensed water is generated, and the exhaust valve automatically opens to discharge the condensed steam and / or condensed water. At the same time, the water level in the valve body rises, and the lever 44 and the float 45 are triggered to open. The condensed water enters the drain valve 4 through the water inlet hole and is discharged through the drain port of the drain valve seat 41. A large amount of condensed water is discharged to the outside of the valve body through the drain nozzle. The drain valve and the exhaust valve are all automatically operated, and the gas and water are completely separated, and the condensed gas and condensed water in the pipeline can be completely discharged.
[0025] In one embodiment, the drain valve and the exhaust valve are provided with external threads, which can be threadedly connected to the second housing 2 .
[0026] In one embodiment, a filter is provided in the medium inlet channel of the first shell 1 .
[0027] Furthermore, for small valve bodies with a caliber of DN15 to DN25, the applicable small drain valve seat has an inner diameter of φ15; for medium valve bodies with a caliber of DN40 to DN65, the applicable medium drain valve seat has an inner diameter of φ20 to φ32; for large valve bodies with a caliber of DN80 to DN100, the applicable large drain valve seat has an inner diameter of φ40 to φ50.
